Class PagerPaginationSupport

public class PagerPaginationSupport
extends java.lang.Object

TODO: Copied From Bucket. There eventually will be a copy residing in atlassian-user if JustinK ever finishes his work! we should get rid of this one and use the atlassian-user if it ever happens. This class stores its items using a Pager - which cannot report the total size of the result. The Pager.getCurrentPage() returns a list of objects currently loaded in memory, which can return a List.size(). This number is imprecise, however, and is used as functional approximation. For various reasons explained in the {#link Pager} javadoc, the only way to gain an accurate total size from a {#link Pager} is by using its iterator and keeping count of each object.

If you have a regular, average sized list of items then use PaginationSupport.
